| 摘 要： | 以丙烯酰胺(AM)和丙烯酸(AA)为主单体,以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、N,N-二甲基丙烯酰胺(DMAM)作为功能性单体,以庚烷为分散介质,表面活性剂SF2810为乳化剂,采用反相微乳液聚合的方法合成了四元共聚物AM/AA/AMPS/DMAM.研究所得的最佳合成工艺条件为:水相中单体浓度为45%,引发剂过硫酸铵加量为单体质量的0.3%,乳化剂加量为油相质量的10%,反应温度为40℃,反应时间为5 h,单体的摩尔比为AM:AA:AMPS:DMAM=52:25:15:8.红外光谱分析证实了四元共聚物的结构.

| Abstract: | A tetrapolymer AM/AA/AMPS/DMAM was synthesized by inverse microemulsion polymerization with acrylamide(AM) and acrylic acid(AA) as main monomers and 2-acrylamido-2-methylpropane sulfonic acid(AMPS) and N,N-dimethylacrylamide(DMAM) as functional monomers.The dispersed medium was heptane and emulsifier was surfactant SF2810 in the inverse microemulsion.The results showed that the optimum synthetic conditions were: the concentration of monomer in aqueous phase 45wt%,the amount of initiator(NH4)2SO4 0.3wt% of m... |
